Actinomycosis: Infections with bacteria of the genus ACTINOMYCES.Actinomycosis, Cervicofacial: A form of ACTINOMYCOSIS characterized by slow-growing inflammatory lesions of the lymph nodes that drain the mouth (lumpy jaw), reddening of the overlying skin, and intraperitoneal abscesses.Actinomyces: A genus of gram-positive, rod-shaped bacteria whose organisms are nonmotile. Filaments that may be present in certain species are either straight or wavy and may have swollen or clubbed heads.Mycobacterium haemophilum: A species of gram-positive, aerobic bacteria that causes granulomatous or ulcerating skin lesions in immunosuppressed persons. This organism owes its name to its requirement for growth of high levels of iron, conveniently supplied as blood, heme, or ferric ammonium citrate.Intrauterine Devices: Contraceptive devices placed high in the uterine fundus.Lymphadenitis: Inflammation of the lymph nodes.Cheek: The part of the face that is below the eye and to the side of the nose and mouth.Dental High-Speed Technique: Dental methods involving the use of DENTAL HIGH-SPEED EQUIPMENT.Neck: The part of a human or animal body connecting the HEAD to the rest of the body.Pelvic Inflammatory Disease: A spectrum of inflammation involving the female upper genital tract and the supporting tissues. It is usually caused by an ascending infection of organisms from the endocervix. Infection may be confined to the uterus (ENDOMETRITIS), the FALLOPIAN TUBES; (SALPINGITIS); the ovaries (OOPHORITIS), the supporting ligaments (PARAMETRITIS), or may involve several of the above uterine appendages. Such inflammation can lead to functional impairment and infertility.Face: The anterior portion of the head that includes the skin, muscles, and structures of the forehead, eyes, nose, mouth, cheeks, and jaw.Vascular Malformations: A spectrum of congenital, inherited, or acquired abnormalities in BLOOD VESSELS that can adversely affect the normal blood flow in ARTERIES or VEINS. Most are congenital defects such as abnormal communications between blood vessels (fistula), shunting of arterial blood directly into veins bypassing the CAPILLARIES (arteriovenous malformations), formation of large dilated blood blood-filled vessels (cavernous angioma), and swollen capillaries (capillary telangiectases). In rare cases, vascular malformations can result from trauma or diseases.Granuloma, Foreign-Body: Histiocytic, inflammatory response to a foreign body. It consists of modified macrophages with multinucleated giant cells, in this case foreign-body giant cells (GIANT CELLS, FOREIGN-BODY), usually surrounded by lymphocytes.Bronchial DiseasesOophoritis: Inflammation of the OVARY, generally caused by an ascending infection of organisms from the endocervix.Pelvic Infection: Infection involving the tissues or organs in the PELVIS.Actinomyces viscosus: A species of ACTINOMYCES found in the oral cavity of man and hamsters. It has been isolated from actinomycotic lesions in swine, cats, and dogs and has been identified as a causative agent of animal diseases.Skin Diseases, Bacterial: Skin diseases caused by bacteria.Colon, Ascending: The segment of LARGE INTESTINE between the CECUM and the TRANSVERSE COLON. It passes cephalad from the cecum to the caudal surface of the right lobe of the LIVER where it bends sharply to the left, forming the right colic flexure.Lung Diseases: Pathological processes involving any part of the LUNG.Tomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Penicillins: A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics.
